Risk of cutaneous squamous cell carcinoma (cuSCC): ≥65yrs, prior skin cancer, chronic sun exposure; if occurs, do excision and evaluate. Perform dermatologic evaluation before therapy, every 2 months during, and consider monitoring 6 months after discontinuation. Monitor for signs/symptoms of new non-cutaneous SCC and other malignancies. Long QT syndrome or QTc >500ms, uncorrectable electrolyte abnormalities, or concomitant drugs that prolong the QT interval: not recommended. Prior to and following initiation or after dose adjustment for QTc prolongation, evaluate ECG and electrolytes after 15 days, monthly during the 1st 3 months, then every 3 months thereafter, or more as clinically indicated. Severe hepatic or renal impairment. Monitor liver enzymes, bilirubin before initiating and monthly during treatment, or as needed. Measure SCr before initiating and periodically during treatment. Monitor for ophthalmologic reactions routinely. Avoid sun exposure. Embryo-fetal toxicity. Females of reproductive potential should use effective contraception during therapy and for at least 2 weeks after final dose. Pregnancy.
